Method and apparatus for producing channel estimate of a communication channel in a CDMA communication system

摘要

A method and apparatus in WCDMA communication system includes extracting pilot symbols (462-5) of (2-M) plurality of communication channels of (1-M) plurality of communication channels based on corresponding 2-M assigned codes (405-436) to produce a plurality (2-M) of extracted pilot symbols (482-96), and combining a first (1) extracted pilot symbol (420) of a first (1) communication channel of (1-M) plurality of communication channels and the plurality (2-M) of extracted pilot symbols (482-96), to produce a combined extracted pilot symbol (498) which is used to produce a combined channel estimate (417) for decoding a first (1) extracted data symbol (414) of first (1) communication channel of (1-M) plurality of communication channels.
